WILLIAM E. THOMAS AND HARRY J. THOMAS, OF FLORENCE, SOUTH CAROLINA.

HYDROCARBON-BURNER.

Application filed July 27,

To (ZZZ whom may concern:

Be it known that we WVILLIAM E. THOMAS and HARRY J. THOMAS, citizens of the United States of America, residing at Floronce, in the county of Florence and fitate South Carolina, have invented new and useful Improvements in Hydrocarbon-Burners, of which the following is a specification.

The object of the invention is to provide a relatively simple and comparatively inexpensive burner adapted for use in connection with heating and cooking stoves and the like and serving as a means whereby the fuel. such as kerosene crude oil, etc., may be effectively vaporized prior to reaching the point of ignition so as to insure complete combustion and hence an economy in the consumption of the fuel, while minimizing the deposit of carbon and hence the tendency of the apparatus to become choked and thus rendered inoperative; a d with this object in view the invention consists in a construction and combination of parts, of which a preferred embodiment is shown in the accompanying drawings, wherein Figure 1, is a side view partly in section of a burner embodying the invention.

2, is a sectional view on the plane indicated by the line 22 of Fig. 1

Fig. 3, is a plan view of the same.

Figs. 4: and 5 are horizontal sections re spcctively on the planes indicated by the lines 4-4 and 5-5 of Fig. 1.

The apparatus embodies essentially a hollow base consisting of a ring or band fitted with a cap plate 11 which is removable and is preferably provided with an embedded ignition tray or trough 12 which,

may have a filling of asbestos or other refractory material as indicated in Figs. 2 and 4, as fuel chamber 18 formed in a casting 14 which is fitted in a seat 15 provided in the wall of saidbase, a vaporizing tube 16 and a burner tube 17. The fuel chamber is supplied with fuel by a feed pipe 18 fitted with a suitable valve 19 of the needle or other preferred type, it being preferable to supply the feed pipe with oil under pressure from either an overhead or elevated tank (not shown) or any equivalent thereof well known in the art and. from said fuel chamber the oil flows through the vaporizing tube which is in communication therewith and preferably consists of an elbow member 20 fitted at 9 6 end as by means of a thread Specification of Letters Patent.

ed joint 21 in the upper end of a fuel chamber and connected at the other end by means of a return coupling 22 with one end of a supplemental elbow pipe section of which the opposite end is connected by a coupling 24 with said burner tube. The bu 161' tube is above and longitudinally of the initial ignition pan or tray 12 and is provided with an orifice 25 through which the fuel escapes after having passed through the vaporizing tube. The outer end of the burner tube may be fitted with a removable cap 26 to permit of access for cleansing purposes when necessary.

Suspended by the supplemental elbow section 23 of the vaporizing tube is a defiector disk 27 preferably having ears 28 which engage the horizontal portion of said pipe section 23 and which serves to spread the flame due to the combustion of the fuel, from the orifice 25.

In spreading the burner, the needle valve may be opened until the vaporizing tube and burner tube have been filled and there has been sufficient overflow to the initial ignition or pan to permit of lighting the oil in said tray, whereupon the valve should be closed until the heat of the flame due to the burni f the oil in said tray has vaporinto tubes whereupon the needle e again opened to continuously cl in its pasibe due to the i of the motor re he burner tube on of the fuel before it rear burner tube and thus presents the fuel the orifice of the burner tube in condition for complete combustion.

The cap pla e 11 is cut away or notched as indicated 29 to fit around the lower end of the vaporizing tube to permit of the removal of said plate when required, and the upper edge the wall of the base is cut away to form an air inlet opening 30 from which the air in turn may escape at opposite sides of the tray or pan 22 through the outlet openings 31 formed in the cap plate beneath the burner tube.

It has been demonstrated in practice that a relatively crude fuel oil may be utilized economically in connection with the burner constructed as herein shown under conditions resulting in the maximum production of heat and that owing to the manner in Which the fuel is conducted to the burner ward members 1 l' ,i. insultin l it or times the vaporize i s the eliminated.

Obviously, however, 1n view of the construction and relative connection of the parts i or members constituting the structure, the cleansing of'the same in the event of deposits can be readily accomplished by the disconnection of the same at the several joints provided, for example, between the members ofthe vaporizing tube and between the extremities of the vaporizing tube and the fuel chamber and burner tube respectively.

The, invention having been described, what is claimed as new and useful is 1 1 1., A hydro-carbon burner havinga 'bas provided with a fuel chamber and means for controlling the admission of fuel to said chamber, a vaporizing tube in connection with the fuel chamber and having a plurality of runs disposed in a common vertical plane in diametrical relation .to and above the base and a burner tube in connection with a the opposite 7 end of said vaporizing tube, and disposed beneath said runs of the vaporizing tube. i ,2. A hydro-carbon burner having abase provided with a fuel chamber and means for controlling the admission of fuel to the said chamber, a vaporizing tube in connection with the. fuel chamber and having a plurality of runs disposed in a common vertical plane in diametrical relation to and above the base and a burner tube in communication with the opposite end of said vaporizing tube and disposed beneath said runs of the vaporizing tube, a deflector being interposed betweenthe burner tube and the lowermost. run of the vaporizing tube.

3. A hydro-carbon burner having a base provided with a fuel chamber, and a valve controlled means for supplying fuel to said chamber, a vaporizing tube consisting of main and auxlhary elbow sectlons connected plane with the said burner tube, and a flame spreader interposed between the burner tube and said horizontal elements on vthe elbow 4E. A hydro-carbon burner having a run consisting of an annular wall and a removable cap plate provided with a diametrically disposed initial ignition tray having a refractoryailler and said base also'being provided with a fuel chamber and valve means'for admissionof fuel. toflthe chamber in combination with av vaporizing tube and a connected burner tube having elements arranged in va common vertical plane in diametrical relationwith the base and above thesaid initial ignition tray.

5. A hydro-carbon. burnerv having a run consisting of an annula-rwall and a. removable cap. plate providedwithv a diametrically disposed initial ignition tray-having a refractory filler and said base alsobeing provided with a fuel chamber andvalved means for admit-ting fuel-thereto and combining with a vaporizingtube and a connected burner. tube having elements arranged in a common vertical vplane in-diametrical relation with the-base andiabove the said initial ignition tra and afiamespreader inter-posed between the said burner tube and those elements of the vaporiring tube which are arranged in a common vertical-plane therewith. v 7 u In. testimony whereof we. aflix i our signatures.
